Tests

tests:
  - text: 不应有未通过的测试
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=10').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isArray 或 isNotArray
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=10').then(data => {  assert.equal(data.assertions[0].method, 'isArray', 'String.prototype.split() returns an Array'); }, xhr => { throw new Error(xhr.responseText); })
  - text: 请选择正确的断言—isArray 或 isNotArray
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=10').then(data => {  assert.equal(data.assertions[1].method, 'isNotArray', 'Array.prototype.indexOf() returns a number'); }, xhr => { throw new Error(xhr.responseText); })
